LLM Temperature- for some days now, I have wondered how many people in the data science community understand the concept of temperature in LLM? or we just apply the temperature, for some of my mates who are business leaders and still build data-centric solutions 😄 - I always want to understand TEMPERATURE in LLM and its so simple to define.
Large language models have become the household name in the Generative AI space, because of how much you can explore from these models. Today, you can mention endlessly the number of models out there - whether -shot or -shot models.
So let us quickly understand temperature - not as a complex parameter but what its impact on LLM models when building applications. temperature defines how LLM responds - How? It helps the LLM or Generative AI models provide either an assertive response which is accurate or a wider range of response(non-assertive) but versatile responses. So the choice of temperature depends largely on your objective.
If you need a very accurate response from the LLM model- you should have your temperature set close -> 0 and where you need a versatile response, your temperature should be close to -> 1.
👉 The formula below is a SoftMax function and the T is the temperature that defines the Yi explores the results of Pi.
Temperature value is between 0 and 1 but what amazes me is the fact that it does define probabilistic value- that is, it does not work like the concept of probability, in fact, its the opposite of probability, so do not assume it's like probability value. In prob, 0 means non-certainty while 1 means certainty however in LLM temperature, 0 technically means certainty and 1 means non-certainty.
My take is don't just apply some fundamental thing in LLM, i think it is very good to dig deeper into the entire concept of every parameter so as to impart knowledge, for me it's not about hype, it's about impacting knowledge.
